shmux

run the same command across many hosts in parallel

shmux is program for executing the same command on many hosts in parallel. For each target, a child process is spawned by shmux, and a shell on the target obtained one of the supported methods: rsh, ssh, or sh. The output produced by the children is received by shmux and either (optionally) output in turn to the user, and/or written to files for later processing. The list of targets may either be specified on the command line or be read from the standard input.
